Problems solved by technology

Although common electrodialysis technology can realize the selective removal of chloride ions, nitrate ions and other ionic compounds relative to non-ionic compounds, it usually leads to a large loss of tobacco ionic active components (nicotine and organic acids), which must be Will lead to decline in the quality of cigarette smoking

Embodiment 1

[0020] Tobacco extract was prepared from tobacco leaves, and 450mL of tobacco extract with a solid content of 8% was installed with 10 pairs of ion-exchange membranes (wherein the negative membrane was Selemion TM Monovalent anions selectively permeate the membrane, and the positive membrane is Selemion TM In the desalination chamber of the electrodialysis device of monovalent cation selective permeable membrane, the effective area is 1 square meter), and in the concentration chamber, add 500mL of tap water; at 15mA / cm 2 Electrodialysis treatment was carried out for 40 minutes under the condition of constant current density and flow rate of 5 L / min.

[0021] After testing, the conductivity of the tobacco extract in the desalination chamber decreased from the initial 14.25mS / cm to 7.68mS / cm after treatment.

[0022] Install 10 pairs of common ion exchange membranes (the anion exchange membrane is a homogeneous anion exchange membrane CJA-2, and the cation exchange membrane is ...

Embodiment 2

[0028] Tobacco extract was prepared from tobacco stems, and 500mL of tobacco extract with a solid content of 8% was installed with 10 pairs of ion-exchange membranes (wherein the negative membrane was Selemion TM Monovalent anion selectively permeates the membrane; the cation exchange membrane is CJC-2 homogeneous cation exchange membrane, manufactured by Hefei Kejia Polymer Material Technology Co., Ltd.) in the desalination chamber of the electrodialyzer; L of sodium sulfate as the starting electrolyte; at 25mA / cm 2 Electrodialysis treatment was carried out for 35 min under the condition of constant current density. After testing, the conductivity of the tobacco extract in the desalination chamber decreased from the initial 16.38mS / cm to 4.5mS / cm after treatment.

[0029] Install 10 pairs of common ion exchange membranes (the anion exchange membrane is a homogeneous anion exchange membrane CJA-2, and the cation exchange membrane is a homogeneous cation exchange membrane CJC-...

Abstract

The invention discloses a method for selectively reducing the Cu content in paper-making process reconstituted tobacco extraction liquid. The method is characterized in that tobacco extraction liquid prepared according to a paper-making process reconstituted tobacco production process is introduced into a freshening room of an electrodialysis device; electrodialysis treatment is performed to reduce the Cu content; in the Cu content reducing process, the Cu removal degree is controlled through the actual Cu content or the electric conductivity change in the freshening room; and meanwhile, the content of nicotine and the total quantity of organic acids in the freshening room are detected so as to inspect the copper ion removal selectivity. The method has the advantages that the Cu content can be effectively reduced; meanwhile, the loss of the nicotine and main organic acids of the tobacco can be avoided; and the smoking quality of the reconstituted tobacco is ensured to the maximum degree.

Description

technical field [0001] The invention relates to a method for selectively reducing the Cu content of reconstituted tobacco leaves by a papermaking method, and belongs to the technical field of production of reconstituted tobacco leaves by a papermaking method. Background technique [0002] In recent years, with the aggravation of the contradiction between smoking and health, the smoking safety of cigarettes has become an important research direction of tobacco science. Due to the pollution of its growth environment and the influence of tobacco planting characteristics, tobacco will contain a certain amount of harmful elements such as heavy metals. For example, Cu is a component of copper oxidase in tobacco, which plays an important role in the redox process of tobacco plants. It has a certain effect on delaying the aging of chlorophyll and enhancing plant resistance. Cu, the harmful element in cigarettes, mainly enters the human body through burning smoke, causing harm to hu...
